Abstract

The utility model provides a three-thread screw-thread and double-head fixed screw with screw teeth of different heights and is mainly used in a screw which is provided with a polygonal flange or an inner polygonal hole for locking. The upper section and the lower section of the screw are respectively provided with two sections of screw rods of different screw thread specifications; wherein, one screw rod is provided with at least three threads of equally divided and arranged screw threads, each lead course is three times as long as the screw distance, and the screw teeth heights of each thread of the screw thread are in different sizes. When the section of screw rod is locked into the constructing hole of a wallboard, the screw rod is provided with multiple screw threads which are equally divided and arranged, so when the screw teeth are locked into a constructing hole, the cement debris which is extruded by agglomeration can be produced, so as to produce better locking effect; no phenomenon of inflating occurs, so the wallboard can not be influenced to break, and the constructing hole interval can also be shortened, which can effectively increase the quantity of the constructing holes which can be pinned at a unit area.

Description

Triple thread double end retaining screw with different height threads
Technical field
The utility model is a kind of three start screw double end retaining screw with different height threads, and particularly a kind of being applicable to locked the double end retaining screw that is fixed in the construction hole on cement wall plate (or other building materials wallboards).
Background technique
At first see also Fig. 1, hang object by general cement wall plate 1 (or other building materials wallboards) nail knot, must be fixed in the construction hole 11 by means of the lock knot of setscrew 2, could utilize bolt 21 to provide the lock knot of object to hang, this has following shortcoming in construction:
1. the means of fixation of setscrew 2, mainly utilize the blind rivet instrument to draw and move bolt 21, make the taper head 211 of bolt 21 front ends force 22 distortion of nail seat to be expanded, making it the card knot is fixed in the construction hole 11, because inflation process often causes breaking of cement wall plate, this is the disadvantage on this kind setscrew uses.
2. the installation of setscrew 2 must could realize by special blind rivet instrument, and this has just increased the inconvenience in the construction.
3. after in a single day setscrew 2 is loaded onto and be consolidated in construction hole 11, as the desire dismounting, extremely is expended man-hour in the future.
4. because locking when constructing hole 11, setscrew 2 easily causes breaking of cement wall or construction hole peripheral because of expansion, so the spacing between the construction hole must keep big spacing, especially limit, corner, therefore the construction hole number that can hammer in the unit area is limited, influence the bond strength between wallboard, but also limited the quantity of prolong knot object.
Summary of the invention
The purpose of this utility model is to design a kind of triple thread double end retaining screw with different height threads for the shortcoming that overcomes above-mentioned setscrew.
The utility model mainly is to be provided with a polygonal flange (or inner polygon hole) for locking usefulness on a screw, and on this screw, hypomere is respectively equipped with the screw rod of two sections different screw thread specifications, make the screw thread that has three-way at least five equilibrium Boulez on the screw rod wherein, stablize non-migration so can keep tight lock, and make its tooth height of thread of each line screw thread be size inequality, make it have the cement detritus that cohesion is squeezed, to produce bigger locking effect, again because of there not being intumescent generation, so can not cause wallboard to break, can shorten the spacing between the construction hole, reduce the area that the knot screw can not be locked in the limit, corner, effectively increase the construction hole number that can hammer in the unit area, also quite easy to be easy during dismounting, help the carrying out of constructing.

Embodiment
As Fig. 2, shown in Figure 3, the utility model mainly be on a screw 3, be provided with one can for locking usefulness polygonal flange 31 (this flange is seized on both sides by the arms with general spanner can lock rotary manipulation), and on this screw 3, hypomere is respectively equipped with the screw rod 32 of two sections different screw thread specifications, 33, and this polygonal flange 31 can be positioned at two screw rods 32,33, and order wherein a screw rod 33 have the screw thread 331 of three-way five equilibrium Boulez, 332,333 (the bar number of this screw thread can be three-way or number such as five lines), making each helical pitch (Lead) is three times [referring to triple thread (Triple Thread) at this] of pitch (Pitch), and make each line screw thread 331,332,333 thread 3310,3320,3330 its tooth height [claiming height of thread (Depth of Thread) again] h1, h2, h3 is a size inequality, so when this section screw rod 33 is locked in the construction hole 11 of cement wall plate 1 (as shown in Figure 5), because of the triple thread on the screw rod 33 331,332,333 are the five equilibrium Boulez (classifies the example explanation at this as with branch cloth such as triple threads, please contrast shown in Figure 4), wherein every line screw thread 331,332,333 be 120 ° spaced apart, the screw thread incision line that has three five equilibriums on the cross section of its transverse section, so can bring into play balanced action, to keep stable non-migration; In addition, each line screw thread 331,332,333 thread 3310,3320,3330 its tooth height are respectively h3, h2, the size of h1 is different, so thread 3310,3320,3330 lock (the aperture D1 that the hole 11 of generally constructing is drilled with when constructing hole 11, its size is about between the external diameter of the path D of screw rod 33 and the high h1 of brachydont, be D＜D1＜D ten 2h1=, can condense institute and squeeze the cement detritus, to produce bigger locking effect, again because of there not being swelling to take place, so can not cause wallboard to break, can shorten the spacing between the construction hole, reduce the area that the knot screw can not be locked in the limit, corner, effectively increased the construction hole number that can hammer in the unit area, and in the future as desire also be easier to when dismantling screw, help the carrying out of constructing.
Fig. 6, shown in Figure 7 is another specific embodiment of the utility model (), wherein screw 4 on, hypomere is respectively equipped with the screw rod 42 of two sections different screw thread specifications, 43, wherein a screw rod 43 has triple thread, and the tooth of its each line screw thread height is different size (this is identical with embodiment shown in Figure 2), just this can be to be located at the top of another screw rod 42 (referring to expose to the screw rod outside the construction hole) (external diameter of this polygonal flange 41 is less than screw rod 42 diameters for polygonal flange 41 of locking usefulness, just can make to add the obstruction that object is not subjected to polygonal flange 41, could tie) with these screw rod 42 locks.
Fig. 8, shown in Figure 9 be the another specific embodiment of the utility model (two), upper and lower section of screw 5 screw rod 52,53 that is equipped with two sections different screw thread specifications respectively wherein, wherein a screw rod 53 has triple thread, and the tooth of each line screw thread height is different size (this is identical with embodiment shown in Figure 2), just this can be to change an inner polygon hole 51 into by the polygonal flange for the position of locking usefulness, be located at another screw rod 52 top of (referring to expose to the screw rod outside the construction hole), and this polygonal hole 51 can provide an interior angle wrench to do locking operation.
In sum, the utility model need not to utilize special blind rivet instrument, be that available general wrench carries out locking operation, and stablize non-migration during screw locking, have cohesion cement detritus again, can produce bigger locking effect, simultaneously because of there not being swelling to take place, so can not cause wallboard to break, and when dismounting is also quite easy easily, so the utlity model has benefits such as practicality, progress.
